No flux conservation in CL inductors PUBLICThere seems to be a problem with inductors in CL: they do not properly conserve flux if their series resistance is set to zero. by signality | updated May 17, 2012 |
|
|
Charge conservation 01 PUBLICComparing charge conservation in real and behavioural capacitors. Unlike real capacitors, in the particular type of behavioural capacitor illustrated, charge is not conserved. by signality | updated May 17, 2012 |
